This unbreaks building when some headers are under a non-standard path.

9720c07f23 gl: Add opengl_version.h to the list of sources 
Adding this private header to the list of sources. We don't want to make
this header public, but we need it in the list of sources otherwise it
won't be included in the tarball. This fixes make distcheck.

This regression was introduced by commit 1a6fe3db

f2af65ee2d gl: add a sync meta for synchronizing across GL contexts 
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.

da0369c66c gstglconfig: Put gstglconfig.h into $(libdir)/gstreamer-1.0/include 
It's architecture dependent and should not be placed into the include
directory as the assumption is that all those headers are architecture
independent.
